IMPROVEMENT IN WASllBOlLERS Specification forming part of Letters Patent No. 130,040, dated July 30, 1872.

To all whom it may concern:

Be it known that I, THURsTEN G. HALL, of Watkins, in the county of Schuyler and in the State of New York, have invented certain new and useful Improvements in Wash-Boiler; and do hereby declare that the following is a full, clear, and exact description thereof, ret'- erence beinghad to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of a wash-boiler, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in whichi Figure 1 is a longitudinal vertical section of my wash-boiler, and Figs. 2 and 3 are enlarged detached views of interior parts of my boiler.

A represents a wash-boiler of any suitable l shape and dimensions, provided with a central cross-partition, B, dividing the boiler in to two compartments, making, as it were, two separate and distinct machines in one, giving an opportunity to wash two kinds ofgoods at the same time. Each of these compartments' is provided with an opening, a, at or near the bottom, for thepurpose of drawing oii the dirty water, said openings being closed by screw-caps C, as shown. Inside of each compartment is placed a false bottom, D, provided with a downwardproj cting.rm, E, around its edges, which restsupon the bottom of the boiler, forming a water-chamber. From the inner side of this falsefbottom D--that is, the side which is against the partition, B-rises a hollowM tapering post, G, extending at' the base nearly across the boiler. On to.p of this post is placed a `cap,H, the crown/of which is beveled at both ends and front, as shown in Fig. 2, and perforated so that the hot water; steam, and sudslwhich pass up fromthe water-chamber below through the post and cap may be thrown in a number of streams upon the clothes. Upon the false bottom D is placed what I call a vacuum-chamber, I, constructed, as shown in Fig. 3, of a plate tting the inside of the boiler, and having a downwardly-projecting rim a suitable distance from its edges, and the rim provided with an opening on each side. This completes the interior fixtures of my wash-boiler. 0n the top of the boileris placed a vessel, J, which is to be illed with cold water when the machine is in operation, its office being to condense the steam, thereby preventingV its escape or the water from boiling over.

The operation isas follows: Fill the waterchamber with water and add a small quantity of soap; then pack the goods to be washed on top of the vacuum-chamber. Place the machine on the stove and the condenser on top of the machine, lling the condenser with cold water. As soon as the steam is generated and has performed its work, it rises, strikes the bottom of the condenser, is condensed, and runs back into the machine. At the samev time the heat below rarefies the air in the chamber I, creating a partial vacuum, and causes the water to return with great force through the clothes. When the water in the condenser gets hot the openings a a at the bottom of the machine are opened, and the dirty water drawn off. The hot water in the condenser is removed by means of the siphon K at one end, andthen clean water is added to the clothes. Fill the condenser again with cold water, and continue the operation until the water runs clear at the bottom after having been driven through the clothes, and then the clothes will be clean.

This machine may be used in combination with any ordinary steam-generator by means of a steam-pipe, whereby live steam may be introduced into this machine Kfor the purpose of heating the water in the water-chamber at the bottom. 'Ihe machine vis well adapted to laundries when attached to a steam-boiler.

`The pipe from the steam-boiler is to' be run H, I claim the vacuum-chamber I, placed imsteam-boiler, as and for the purposes herein mediately over the Water-chamber7 substanset forth.
